Anittha’s Thonglor house is quite stylish. It is just far enough away from the traffic of Thonglor that you are not disturbed, but close enough (1 minute walk) that you can easily catch a cab. If you like Bangkok street food then you are in luck because there is a great selection of food carts on Soi 9. Nearby restaurants include Japanese, Argentinian, US and, of course, Thai selections.
There are some great shopping areas close by as well as lots of nightlife.
